PROBLEM TO BE SOLVED: To save energy by changing the operating speed of an elevator through a process of controlling the target speed of a motor controller by time fuzzy sets and size fuzzy sets, in speed control of an escalator. SOLUTION: When an escalator operating value for saving energy and an estimated value are determined in a case where the operation of an escalator is changed, they are estimated by using passage history. The passage history of the escalator is analyzed by the fuzzy theory. The target speed for saving mean energy is determined while there are a few passengers, and this target speed is selected on the basis of fuzzy sets indicative of the estimated value of the case of a few passengers. The demanded target speed is given by T-norms of the time fuzzy sets and the size fuzzy sets. Accordingly, the target control speed can be obtained in the wide range from the minimum speed to the maximum speed by averaging the T-norms. |
